Building Of OCOKA Model For Tactical Terrain Analysis And Design Of Analysis System

Technologies have been changing our lives constantly, but not our thoughts. The inappropriate application of modern information technologies in military brings more problems than it has solved. Technologies give impetus to the advancement of times. If we cannot keep pace with the times, the war we have been putting our efforts to prepare will be possibly outdated and never start. The core aim of applying information technologies in military is to get knowledge of "the other side of the hill", release the fog of battle field, and finally reduce the uncertainties in the command and control and task implementing. The purpose of establishing tactical terrain analysis system is to give military commanders a better understanding of the battle field, help them figure out the characteristics of it and provide bases for the operation plan. Most of the current tactical terrain analysis systems in our country were established in 1980s and 1990s, which have not been commonly used, failing to meet the expectations of military commanders. The deep reason for its uncommonly usage is the lack of the traction of military theories and the inappropriate application of technological means. The direct reason is that there is no standardized series of terrain analysis methods and reliable mathematical model. With the development of GIS, the great challenge for us is how to set up a generalized, practical and standardized tactical terrain analysis system, guided by the vigorous military theories. Aiming at laying down the theoretical foundation for the reestablishment of our military tactical terrain analysis system, the author takes the studies on modern war theories and filed field manual as staring point of this paper, how to describe, extract, analyze and express terrain characteristics as the core content, OCOKA (the military terms for the Observation and Fields of fire, Cover and Concealment, Obstacles, Key Terrain, Avenues of Approach) as the clue and engineering system design as the outcome.Setting up tactical mathematical model is predicated on the establishment of terrain analysis software system. In Chapter 2, the author combines American military experience and our military features and proposes a tactical terrain analysis model-OCOKA, based on two American field manual. The relations between OCOKA and traditional military principles and modern wars are also discussed in this chapter. The third chapter is on how to turn the conceptual model of OCOKA into a mathematical model. In the beginning of the chapter, the overall design principles of the model -building are give, namely, "Host/Guest clear separation" and "Human / Rorbort appropriate division of works " Next, OCOKA is established, the basic concepts are defined, the constrained conditions are analyzed, the mathematical formula is proposed, the evaluation factors are designed and finally comparison with the current terrain analysis systems is made. The fourth chapter is about the process of seeking solutions of OCOKA as well as its ways of application: firstly, introduce the input data and output results; secondly, the basic steps of how to apply the model are discussed in details; thirdly, the ways of seeking solutions as well as expressions of the data are given with the accompany of five illusions. Chapter 5 is focused on how to transfer the mathematical model, ways of solution seeking, and the application process of OCOKA into computer program. In this chapter, the key technology used in OCOKA-GIS is introduced and the overall structure of the tactical terrain analysis system as well as the main processes and data base of the five OCOKA modules are designed. The last chapter, Chapter 6, does some reviews on the research work of the paper and looks to the future of the military terrain analysis systemsIn 1980s and 1990s, combat modal-building was used to be a craze. It had been left in a corner since the fever went down. In the new century, we have a long way to go in setting up mature terrain analysis system. It is hoped that the proposition of OCOKA can be the beginning of a new page and open another window for studies in tactical terrain analysis. The concept of modal building, the mathematical modal and ways of seeking solutions in this paper are relatively new in this area, which must have some deficits waiting for the tests of practice. However, bringing in new thoughts as well as arising debates and discussions to promote the development of tactical terrain analysis system is the very purpose of this paper.
